Signature of a polyamorphic transition in the THz spectrum of vitreous GeO(2)

The THz spectrum of density fluctuations, S(Q, ω), of vitreous GeO(2) at ambient temperature was measured by inelastic x-ray scattering from ambient pressure up to pressures well beyond that of the known α-quartz to rutile polyamorphic (PA) transition. We observe significant differences in the spect...
